Application May 28, 1954, Serial No. 433,149

1 Claim. (l. 46-220) This invention relates to toy hoop devices, and more particularly to an improved trundle device for rolling and guiding hoops.

A main object of the invention is to provide a novel and improved hoop trundle device which is simple in construction, which is easy for a child to use, and which is so constructed that it may be employed with hoops of different sizes and will enable a child to propel a hoop forwardly on the ground by merely pushing the trundle device.

A further object of the invention is to provide a novel and improved hoop trundle device which is inexpensive to construct, which is durable, and which is foldable to a compact size.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

Figure 1 is a perspective view showing an improved hoop trundle device according to the present invention, engaged with a hoop.

Figure 2 is an enlarged vertical cross sectional detail view taken on the line 2-2 of Figure 1.

Figure 3 is an enlarged cross sectional detail view taken on the line 3-3 of Figure 1.

Figure 4 is an enlarged cross sectional detail view taken longitudinally through the connection joint between the segments of the main staff of the hoop trundle device of Figure 1.

Referring to the drawings, 11 generally designates the improved hoop trundle device, said trundle device comprising a main staff indicated generally at 12, said main stafi comprising a lower section 13 and an upper section 14, the sections 13 and 14 being made of rod-like material which are flattened at their ends, as shown at 15 and 16, said flattened ends being superimposed, as shown in Figure 4, and being detachably secured together by the bolts 17, 17 and wing nuts 18, 18. The upper section 14 is provided at its end with the handle 19. The lower section 13 is formed at its lower end with the elongated transverse loop 20, said loop being open at 21 to allow the loop to be engaged with a hoop 22.

Designated at 23 is an auxiliary stafi element which is formed or" rod-like material and which has a flattened end 24 which is superimposed on a flattened portion 25 provided on the lower main staff section 13. The flattened end 24 of the auxiliary staff section 23 is pivotally connected to the flattened portion 25 of the main staff section 13 by a bolt 26 and is secured in adjusted angular position by means of a wing nut 27 engaged on the bolt 26.

nited States Patent The auxiliary staff section 23 is formed at its free end with a vertically elongated loop 28 which is open at 29 to receive a portion of hoop 22 located at a substantial distance above the portion thereof engaged in the loop 20.

As will be readily apparent, the angular spacing between the auxiliary staff section 23 and the lower main staff section 13 may be adjusted in accordance with the size of the hoop to be propelled.

in using the device, the auxiliary staff section 23 is first adjusted to the desired angular relationship with respect to the lower main staif section 13, the auxiliary section being locked in adjusted position by tighting the wing nut .27. The loops 28 and 20 are then engaged with the hoop 22 in the manner illustrated in Figure 1, whereby the child may propel the hoop by merely grasping the handle 19 and by pushing on the device, causing the loop to be trundled forwardly on the ground in the well known manner.

By employing the spaced loops 2t and 28, the hoop is steadied at two widely .spaced points on the hoop, giving maximum control of the hoop to the user of the device, and eliminating the possibility that the hoop will break away from the child and will be followed into the street with consequent risks of injury to the child from trafiic. By means of the spaced loops 20 and 28, the hoop may be started from a standing position, enabling the child to roll the hoop without any considerable amount of preliminary practice.

When the device is not being used, it may be folded to a relatively compact condition by loosening the wing nuts 18, 18, removing one of the bolts 17, and folding the upper main staff section 14 to a position adjacent the lower staii section 13.

While a specific embodiment of an improved hoop trundling device has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claim.

What is claimed is:

A foldable hoop trundle comprising a main staff, said main stafi consisting of a lower section and an upper section detachably secured together in alignment, a transversely extending elongated open loop at the end of said lower section adapted to engage a hoop, an auxiliary staff element pivotally connected to the upper end of said lower section, means for clamping said auxiliary staff element to said lower section so that said auxiliary stafi element extends at an angle with respect to said lower section, means for changing said angle, and a further transversely extending elongated open loop on the end of said auxiliary staff element adapted to engage the hoop at a substantial distance from the first-named loop, said open loops having a flattened oval configuration, whereby said loops may be so spaced from each other that the hoop cannot become disengaged therefrom in use, and whereby said trundle is adjustable for different sizes of hoops and for different heights of the users thereof.
